[Electroencephalography in clinical research into psychoses (author's transl)].

At present EEG investigations in heterogenous acute schizophrenic and psychotic syndromes suggest changes in the regulating, reticulo-thalamo-cortical, functional system. One may further assume that cerebral functional changes consist of a dissociation of normally closely linked functional systems. In favor are findings in functional psychoses ("Funktionspsychosen"), also the dissociation of usually coordinated systems in normal psychologic changes during going to sleep and REM stages of dreams. A further thalamohippocampo-reticulo system which might act in parallel to the activating reticular system has become important in EEG research into psychoses. Changes here probably in part of focal EEG phenomenon localized in the temporal region. Here, too, EEG findings in schizophrenic syndromes requiring further proof emerge.
